void LCD_display_char

(

char

character

)

Display the specified character at the cursor position and move the cursor on 1 position.

Parameters:

character

The 8 bit character to be displayed

The display has 40 characters of memory for each line, irrespective of the number of characters displayed, so it is perfectly possible to write 'off the right' of a display. The characters there would be seen in a subsequent scroll left.

This function will return as soon as the command is issued, the display may internally take an unspecified time to execute the command.

void LCD_display_int16

(

int16_t

val

)

Display a signed 16 bit value as an optional minus sign followed by up to three characters.

Parameters:

val

The 16 bit value to be displayed

Display an 16 bit signed integer on the LCD, as an optional minus sign followed by a series of up to five decimal characters. Doesn't output leading zeroes, so number of characters transmitted may vary.

Parameters:

nibble

The 8 bit value to be displayed

Display the lowest 4 bits of an 8 bit unsigned value as one ASCII character 0-9,A-F The upper bits of the value are ignored.

Internal command used within the library to sens a byte over the two wire system.

Parameters:

rs

1=data, 0=control

lcd_data

8 bit value to be sent to the LCD

void setaddress_lcd

(

uint8_t

row,

uint8_t

column

)

Move the address pointer to the memory address corresponding to the row and column specified.

Parameters:

row

Row number counting from 0

column

Column number counting from 0

Moves the address pointer to the address specified, so new text will be inserted at this new address. The blinking cursor will not be moved.

The display has 40 characters of memory for each line, irrespective of the number of characters displayed.

This function will return as soon as the command is issued, the display may internally take an unspecified time to execute the command.
